Knock Knock / Knock Knock

Knock Knock
Knock Knock

This idea comes from the sound chips game and jigsaw puzzle we played when we were young, in which the length of the chips decides the sound of them.The traditional playing only gives children seven notes so that they can make an easy song by themselves. But while playing our “Knock Knock” they can learn 4 kinds of simple chords besides those fundamental notes.The fundamental notes can be crossed together to produce a chord. In our game, children need to cooperate with others.Only by cooperating can they accomplish a wonderful song.Also, we design the product with various colors to attract children. An integral song is played by foot.
